I can support earlier report by GURU FAX.
Latest anti-spyware DAT File version 01.200708.2245 appears to have fixed the problem with MSRDO20.DLL reporting as a trojan.
I have just now run the ZA spyware scan twice. Both scans reported
nothing detected.

Re: Win32.Backdoor.Revell.110 ???

Had the same on my scan: on 21 AUG 2007 my ZA Security Suite 7.0.337.000 flagged Win32.Backdoor.Revell.110. After deleting it it turned out that my Registry Mechanic didn't want to boot any more. In stead I got a Windows Install Wizard window that kept insisting that I should reinstal my MS Office 2002. This didn't revive Reg Mechanic. Furthermore I noticed that the Windows Update from the MS website (the only thing I have to use IE for BTW) does download, but does not want to install the updates. Had to do that by downloading the MS updates through the developers portal, download them and boot them on my desktop.

All I want to say: it is essential that we find out whether the MSRDO20.dll flag by Za is genuine. Deleting the dll is does give a lot of hassle and disrupts your system.

Re: Win32.Backdoor.Revell.110 ???

Yes I got all this too today, but I believed it, because (a) I had recently installed quite a lot of stuff including Adobe Photoshop CS3, Illustrator, Magical Defrag, etc (involved removing bootleg Adobe progs) and (b) my Win XP HP Pavilion ZD8000 notebook stopped connecting to my wireless network properly, (actually it connected, then after a while in the same session it would not work, could not connect (apparently failed to get (DHCP?) IP address from ADSL Router/ISP). It is still stuck like this after ZA 'detected' MSRDO20.DLL as Win32.Backdoor.Revell.110, and I deleted MSRDO20.DLL and all the associated registry entries (via ZA) (although not rebooted yet). I connected another (slightly dodgy XP) machine to the same ADSL router via blue cable and it works fine. Although I still have this severe problem with the Notebook (no Internet connectivity), I now suspect this is more likely than not an autoimmune response (ie false positive), but the possibility remains that malware is stuffing ZA (somewhat like HIV) and playing with us. (just for the paranoid?
